The odoriferous compounds used according to the invention have a typical smell of cedar with a characteristic note of musk. They serve e.g. for the preparation of precious wood compositions with a new and original perfume nuance and an enhancing and fixing elfect.

The compounds used according to the invention may be obtained, for example, by reacting the alkali compounds of cyclododecauol with alkylor alkenyl halides or neutral sulfuric acid esters.

EXAMPLE 1 Precious wood complex:

250 parts by weight of cyclododecauol methyl ether 200 parts by weight of cyclododecanol ethyl ether 50 parts by weight of cyclododecauol methallyl ether 20 parts by weight of -iraldein 80 parts by weight of delta iraldein 50 parts by weight of oryclone 50 parts by weight of vetiveryl acetate 170 parts by weight of liquid cedryl acetate 30 parts by weight of guaiyl acetate 100 parts by weight of cedar ketone 1000 parts by weight atet 3,281,474 Patented Get. 25, 1966 EXAMPLE 2 The preparation of the compounds used in accordance with the invention may be carried out as follows:

(a) Cyclododecanol methyl ether The sodamide was separated by suction filtration from a benzene suspension and heated in 200 g. of xylene to boiling point while stirring. During the course of one hour, the cyclododecauol, dissolved in the remaining xylene (1300 g.), is added to the boiling suspension. After boiling for another 2 hours, the evolution of NH ceases and dirnethylsulfate is carefully added dropwise. A vigorous reaction sets in. The mixture is thereafter stirred for another 4 hours and boiled, poured onto ample ice and g. of concentrated sodium hydroxide, washed once with H 0 and distilled.

Crude cyclododecauol methyl ether: 180 g. (containing cyclododecauol) B.P. 99106 C.

The crude ether is freed from unreacted cyclododecauol in a 40-iayered disc column by distribution between methanol and gasoline (3040 C.) in the ratio of 1:10:10. From the gasoline phase there are obtained (all according to the OCHg content of the crude ether) to g. of cyclododecauol methyl ether of B.P. 86 to 92 C., D, 0.9082, 11 1.4746 (percent OCH 13.1 (theory 15.7)). The cyclododecauol (20 g.) isolated from the methanol phase can be used again.

(17) Cyclododecanol allyl ether After the above-described preparation of the sodium compound of cyclododecauol, 1.2 mol=145 g. of allylbromide are added, boiled for 24 hours, poured onto water, and the crude ether is distilled after washing. The ether is immediately extracted as above. From the gasoline phase there are obtained 130 g. of cyclododecauol allyl ether of B.P. 129-131 C. at 3 mm. Hg and the constants D 0.912, n 1.4839.

The methanol phase still yields about 50 g. of unchanged cyclododecauol.

In a corresponding manner there can be prepared the other others.

I claim:

1. Aliphatic cyclo-dodecanol ethers, wherein said aliphatic radical is a member selected from the group consisting of saturated alkyl containing up to 4 carbon atoms, 'allyl, crotyl, and methallyl radicals.

2. Cyclododecanol methyl ether.

3. cyclododecauol ethyl ether.

4. cyclododecauol isopropyl ether.

5. cyclododecauol allyl ether.
